They were probably comparing cartridges(7MM and 300) and got them mixed up when they went to put em back in the box.
Wouldn't be the first time. and yeah that different sound was a 7mm going down a .308 bore.
Yup I bet that was it as well. No way a 7mm would get in with a 300 at the Hornady plant. That definitely sounds like a gun shop mix up. I wouldn;t worry about anything. Toss that brass and load up the rest.
